kubischem

Kubischem is a term used in the conceptual language of geometry to denote a class of cubic geometric constructs and transformations. The name derives from kubisch, the German word for cubic.

In this use, Kubischem objects are typically defined by third-degree polynomial equations or by coordinate functions that are cubic polynomials. Examples include cubic surfaces in three-dimensional space and cubic transformations in which each output coordinate is a cubic polynomial of the input coordinates.

In computer graphics and algebraic geometry, cubic forms and cubic surfaces provide smooth, complex shapes and invariants under certain operations; Kubischem serves as a descriptive label for such cubic phenomena. The term is not a standard designation in mainstream English-language mathematics and may vary in emphasis across texts.

Related concepts include cubic forms, cubic surfaces, cubic curves, and cubic Bézier patches.
